/*
 * To help understand the following definitions, this block of comments
 * provides information on Cheetah's E$.
 *
 * Cheetah supports three different E$ sizes (1MB, 4MB, and 8MB). The
 * number of E$ lines remains constant regardless of the size of the E$
 * as does the subblock size, however the number of 64-byte subblocks per
 * line varies depending on the E$ size.
 *
 * An E$ tag (for an E$ line) contains an EC_tag field, corresponding to the
 * high order physical address bits of that E$ line's contents, and 1 to 8
 * EC_state fields, indicating the state of each subblock. Due to the E$ line
 * size variance depending on the total size of the E$, the number of bits in
 * the EC_tag field varies as does the number of subblocks (and EC_state
 * fields) per E$ line.
 *
 * A 1MB E$ has a line size of 64 bytes, containing 1 subblock per line.
 * A 4MB E$ has a line size of 256 bytes, containing 4 subblocks per line.
 * An 8MB E$ has a line size of 512 bytes, containing 8 subblocks per line.
 *
 * An E$ tag for a particular E$ line can be read via a diagnostic ASI
 * as a 64-bit value.
 * Within the E$ tag 64-bit value, the EC_tag field is interpreted as follows:
 *	- for a 1MB E$, the EC_tag is in bits <43:21> and corresponds
 *		to physical address bits <42:20> (bits <41:19> for Cheetah+)
 *	- for a 4MB E$, the EC_tag is in bits <43:23> and corresponds
 *		to physical address bits <42:22> (bits <41:21> for Cheetah+)
 *	- for an 8MB E$, the EC_tag is in bits <43:24> and corresponds
 *		to physical address bits <42:23> (bits <41:22> for Cheetah+)
 * Within the E$ tag 64-bit value, the EC_state field(s) is(are) interpreted
 * as follows:
 *	- for a 1MB E$, EC_state0 is in bits <2:0>
 *	- for a 4MB E$, EC_state0 is in bits <2:0>, EC_state1 is in
 *		bits <5:3>, EC_state2 is in bits <8:6>, EC_state3 is
 *		in bits <11:9>
 *	- for an 8MB E$, EC_state0 is in bits <2:0>, EC_state1 is in
 *		bits <5:3>, EC_state2 is in bits <8:6>, EC_state3 is
 *		in bits <11:9>, EC_state4 is in bits <14:12>, EC_state5
 *		is in bits <17:15>, EC_state6 is in bits <20:18>,
 *		EC_state7 is in bits <23:21>
 * Note that each EC_state field contains a value representing the state
 * of its corresponding subblock.
 *
 */
/*
 * Jaguar changes from Cheetah/Cheetah+ Ecache:
 *
 * The Jaguar Ecache is similiar to that used for Cheetah/Cheetah+ with a
 * couple of differences :
 *	- Jaguar Ecache only comes in 4MB and 8MB versions.
 *		- 8MB E$ has 2 64 byte subblocks per line.
 *		- 4MB E$ has 1 64 byte subblock per line.
 *
 * An E$ tag for a particular E$ line can be read via a diagnostic ASI
 * as a 64-bit value.
 * Within the E$ tag 64-bit value, the EC_tag field is interpreted as follows:
 *	- for a 4MB E$, the EC_tag is in bits <41:21> and corresponds
 *		to physical address bits <41:21>
 *	- for a 8MB E$, the EC_tag is in bits <41:22> and corresponds
 *		to physical address bits <41:22>
 *
 * The Jaguar E$ tag also contains LRU field in bit <42> which must be
 * masked off when the tag value is being compared to a PA.
 *
 * Within the E$ tag 64-bit value, the EC_state field(s) is(are) interpreted
 * as follows:
 *	- for 4MB E$, EC_state0 is in bits <2:0>
 *	- for 8MB E$, EC_state0 is in bits <2:0>, EC_state1 is in bits <5:3>.
 * Each EC_state field contains a value representing the state of its
 * corresponding subblock.
 *
 * Note that the subblock size and state values are the same for both
 * Cheetah/Cheetah+ and Jaguar.
